Job description

We are looking for a Lead / Staff Engineer (Web Game Platform) to build and operate a scalable platform for mobile-first HTML5 web games. This role owns the platform layer end-to-end—driving architecture, SDKs, tooling, and performance standards—so multiple game teams can ship quickly, consistently, and with minimal duplication.

Candidates across senior and leadership levels are welcome to apply. Scope and responsibilities may be adjusted based on candidate’s experience, expertise, and leadership capabilities.

Responsibilities

• Design and own a modular runtime/plugin system (dependency management, lifecycle, configuration, isolation, graceful fallback).
• Build and evolve reusable game frameworks that standardize core patterns (state, events, config-driven logic) while remaining extensible.
• Define and enforce platform contracts, including API stability, backward compatibility, and upgrade policies.

Tooling, Build & Release

• Develop and maintain a multi-package SDK ecosystem (private npm, versioning, changelogs, CI/CD, release automation).
• Own bundling strategy (Rollup/Webpack/Vite): code splitting, tree-shaking, and bundle optimization.
• Implement safe rollout strategies across projects (canary releases, compatibility checks, automated validations).

Performance & Quality

• Establish platform-wide performance budgets (bundle size, load time, memory, FPS stability).
• Provide shared observability tools (logging, telemetry, error handling standards).
• Improve developer experience through documentation, templates, and reference implementations.
• Partner with game and compliance teams to translate recurring needs into reusable platform features.
• Lead design reviews, mentor engineers, and drive platform roadmap and standards.

Requirements

• Bachelor's degree or above in computer science, software engineering, Game Development or a related technical field.
• 6+ years of Web / Game Development experience in high-concurrency engineering environment such as e-commerce, gaming and social platforms.
• Demonstrated experience building and maintaining SDKs/frameworks used across multiple projects.
• Strong understanding of modern build systems (Rollup, Webpack, Vite) and performance optimization.
• Strong system design skills for modular, scalable architectures (plugins, lifecycle, dependencies).
• Experience profiling and optimizing performance in mobile web environments.
• Ability to contribute to technical direction and engineering best practices through areas such as architecture discussions, code reviews, mentoring, or technical decision-making.

Nice To Have

• Experience with web game engines (e.g. Cocos Creator, Phaser, PixiJS).
• Familiarity with iframe-based integrations and varying host environments.
• Experience with WebGL performance tuning and asset pipelines.
